The aim of this study is to identify the impact of different steam explosion treatments on the thermal degradation of cellulose fibers. The intensities of the treatments were defined by a severity factor (SF), based on the residence time and the process temperature. The results obtained show that thermal degradation of cellulose fibers is limited when the severity factor value is below 4.0. At higher intensities, determination of thermal degradation products shows a significant increase of the hydroxymethylfurfural (5-HMF) amount when increasing the intensity of the treatment. When the severity factor reached 5.2, TGA analysis shows that the increase of degradation products is coupled to an increase of the char level meaning a strong degradation of the cellulose. [less ▲]

On the basis of synchronic and diachronic data analysis, the volume takes a close look at the synchronic layers of binominal size noun and type noun uses (a bunch/a load of X; a sort of X; a Y type of X) and reconsiders the framework of grammaticalization in view of issues raised by the phrases under discussion. As a result, a construction grammar-approach to grammaticalization is developed which does justice to the syntagmatic lexical, or collocational, reclustering observed in the data within an eclectic cognitive-functional approach.

Les récents soulèvements arabes ont conduit nombre de journalistes et experts à se focaliser sur le rôle décisif d'Internet dans les mobilisations. Autant les usages contestataires d'Internet dans le monde arabe étaient jusque là largement ignorés, par les médias traditionnels (occidentaux ou non) mais aussi par le monde académique, autant désormais on observe une surenchère sur le rôle révolutionnaire des médias sociaux, souvent agrémentés de titres accrocheurs : « Révolution 2.0. », « Révolution Facebook », « Cyber-révolution »... À partir d'une recherche de doctorat portant sur les usages citoyens et contestataires d'Internet par les Tunisiens, je souhaiterais ici apporter un éclairage plus nuancé sur le rôle d'Internet dans ce petit pays du Maghreb où le « printemps arabe » est né, en prenant en considération à la fois son importance et ses limites. Je commencerai par poser le contexte contraignant dans lequel les internautes tunisiens devaient évoluer sous le régime de Ben Ali. Ensuite, je retracerai l'évolution des usages citoyens et contestataires d'Internet depuis la fin des années 90 jusqu'à aujourd'hui. Enfin, à la lumière de cette courte mais déjà riche histoire, je proposerai quelques éléments d'analyse du rôle d'Internet dans la conjoncture critique de décembre 2010-janvier 2011 en Tunisie.

Introduction: The study of normal structures of the sheep’s brain is very important to understand pathological changes caused by the bluetongue virus in the fetus’s brain at various stages of the gestation. Bluetongue is an arthropod-borne viral disease of domestic and wild ruminants. The serotype 8 is responsible for outbreaks in Northern Europe in 2006. This virus causes lesions in the brain of fetuses as hydrancephaly and porencephaly. The aim of this work is to improve knowledge of anatomy and histology of the central nervous system of the sheep. Methods: Seven heads of adult sheep and one from a fetus aged 4,5 months were used. All heads were first opened in the frontal area using bone’s saw and immerged in a formalin solution for 10 days. After a good fixation, the brains were extracted and sectioned. Transversal, frontal and sagittal sections were realized. The sections of two brains were stained with Berlin-blue and treated to be embedded in methylmetacrylate for gross morphology. The different parts of the 6 resting brains were then embedded in paraffin, cut and the histological sections were stained with haematoxylin/eosin, cresyl violet or by use of silver impregnation. Results: Gross morphological examination of the brains embedded in methylmetacrylate showed the detailed anatomy of the different parts. The staining with haematoxylin/eosin permitted to differentiate the grey matter, the different nucleus and the layers of cerebral and cerebellum cortex. The cresyl violet technique permitted to visualize the Nissl bodies and the silver impregnation revealed nerve fibers. In the fetus brain, blood vessels were very numerous in the brainstem, the cerebellum and the cerebrum. The grey matter was less organized and looser. Conclusion: This work establishes an anatomical and histological approach allowing future studies in ovine fetuses with and without brain lesions potentially caused by the bluetongue virus. [less ▲]

[4+2] thermoreversible Diels-Alder cycloaddition has been used to crosslink star-shaped poly(ε-caprolactone) in order to produce networks based on strong carbon-carbon covalent bondings. Depending on the nature of the Diels-Alder reactants, these bonds can be thermoreversibly broken, allowing re-processing of the polymer matrix. [less ▲]

On 7 and 8 December 2011, students, researchers, and conservationists with a vested interest in golden-headed lion tamarins (Leontopithecus chrysomelas; GHLTs) gathered at the State University of Santa Cruz (UESC; Ilhéus, Bahia, Brazil) for the symposium `Golden-Headed Lion Tamarin Research in the 21st Century: Recent Advances and Potential Areas of Future Research´ with the aim of sharing recent work and discussing potential future avenues for research. Within the last 5 years, several doctoral dissertations and masters theses were completed that focused on the biology, ecology, and/or conservation of GHLTs in addition to the ongoing work of established scientists who have devoted their professional lives to the study of this species and the Atlantic Forest. However, language barriers and the fact that many members of the GHLT community are based at institutions throughout the world have complicated widespread access to these results and collaborations among researchers. The primary goals of this symposium were to (1) promote the exchange of existing information, (2) contribute towards a better synchronization of research efforts, and (3) identify important steps for more efficient/ collaborative conservation efforts for GHLTs and their habitat. This symposium brought together 30 participants from 12 institutions in Brazil, Belgium and the USA and allowed for the dissemination of information to the global GHLT community, compilation of recent advances in research, and identification of gaps in knowledge of GHLT biology, ecology and conservation, which ultimately fostered discussions on how attendees could collaborate to fill knowledge gaps.

In this study we report the investigation of the nightglow molecular oxygen emissions of Venus in the visible spectral range, observed by the VIRTIS instrument (Visible and InfraRed Spectral Imaging Spectrometer) on board the Venus Express spacecraft. The Herzberg II system was detected in the range 0.4-0.7 µm. The observed bands peak at 95-96 km altitude, with a limb mode intensity of 15-20 kR for the strongest band, similar to that seen in previous observations. Simultaneous observations in the visible and IR [O2 (a-X) 1.27 µm band] were obtained in March 2007, and the two systems are similar in peak altitude. In addition, three bands of the O2 Chamberlain system, at 0.558, 0.604, and 0.657 µm were detected. They are well detached from the Herzberg II bands, and more distinct than reported in previous observations (Garcia Munoz et al., 2009). A simulated spectrum is obtained using the DIATOM code, allowing accurate reproduction of the observed VIRTIS mean spectrum. [less ▲]

Surface-charged nanofibers were prepared by electrospinning technique (ESP). For this purpose, a copolymer bearing carboxylic acid functions was added to a poly(D,L-lactide) solution just before ESP process. In a basic medium, negative charges were therefore revealed on fiber surface. By deposition of positively charged particles or polyelectrolytes, surface properties of the fibers could be tailor-made for a specific application. This versatile method can, for example, be applied to the preparation of new biomedical scaffolds. [less ▲]
